Why everything reads the same now

Read five agency websites, five SaaS homepages, or five LinkedIn posts in any B2B category, and the sensation is oddly specific: not that any of it is badly written, but that all of it is written the same. Competent, fluent, structured, and completely interchangeable. Swap the logos and nothing breaks.

This has a mechanical explanation. Language models produce statistically likely language — that is the objective they are trained on. When close to nine in ten marketers use AI daily, mostly through the same handful of tools, mostly with prompts that differ only in the noun, the outputs converge on the same statistical centre. Meanwhile 2026 industry reporting puts marketing content volume up roughly 85% year on year. More content, drawn from a narrower stylistic range.

The evidence that AI flattens brand voice

This could easily be an aesthetic complaint dressed as analysis, so it is worth noting that the effect has been measured.

The cleanest result comes from a natural experiment: Italy's temporary ban on ChatGPT. A study examining brand output across that period found that when brands lost access to the tool, their Instagram content became measurably more distinct — in vocabulary, in sentence structure, and in meaning. Removing the AI increased differentiation. That is a difficult finding to explain away.

On the receiving end, Capgemini's consumer sentiment tracking found trust in AI-generated content fell from 73% to 55% between 2023 and 2025, and the decline held across every age group. The interesting part is that this is not mainly about detection. Most people cannot reliably identify a specific piece as machine-written. What they accumulate is a general sense that nothing they read is telling them anything.

What is actually missing from AI-written content

It is tempting to frame this as a style problem and reach for a tone-of-voice document. That rarely fixes it, because the deficit is not stylistic. Four things are missing from generated content, and none of them are about how sentences sound.

Specifics that exist only inside your business

What a project actually cost. How long it really took. The conversion number before and after. The client who churned and why. This material is not in any training corpus because it has never been published — which is exactly why it is the most valuable thing you own.

Positions someone could disagree with

Generated content trends toward the uncontroversial, because the statistical centre of any topic is the consensus. But a claim nobody would dispute carries no information. "Choose the right platform for your needs" is a sentence that says nothing. "Most businesses on a headless CMS did not need one, and are now paying a developer for changes they used to make themselves" is a position, and someone will argue with it.

Things you refuse to do

A brand defined only by what it offers is defined weakly. What you decline — clients, project types, tactics you think are wrong — locates you far more precisely than another list of services.

Being wrong in public

Mistakes and reversals are among the most credible things a business can publish, and almost nothing generated will produce them, because the model has no history to be wrong about.

Using AI without dissolving into it

None of this argues for abandoning the tools. The useful distinction is between AI as a source and AI as an instrument.

As a source, the prompt is thin — "write a blog post about X" — and the output is published close to unchanged. Everything in it came from the model, which means everything in it also exists in a hundred competitors' versions.

As an instrument, you supply the substance: your numbers, your transcripts, your positions, your customer's actual words from a sales call. The model restructures, tightens, and edits. The distinctiveness was yours and survives, because the raw material never came from the training data.

A practical test before publishing: could a direct competitor publish this exact piece by changing only the brand name? If yes, nothing in it is yours. That single question catches most of it.

Why this is getting more valuable, not less

There is a second-order effect worth understanding. As AI assistants increasingly mediate discovery, being quotable matters more. An assistant summarising your category will reach for specific claims, real numbers, and clear positions, because those are what compress into an answer. Generic content compresses to nothing — there is no there to extract.

So the same qualities that make writing recognisably yours make it more likely to be cited, which is the mechanism we cover in generative engine optimisation and how to check in tracking brand visibility in AI search. Distinctiveness stopped being a purely aesthetic concern and became a distribution one.

Where to start fixing it

Not with a rewrite. Take the three pages that matter most — usually the homepage, the main service page, and whatever ranks best — and run the competitor test on each. Then add back one specific number, one position someone could argue with, and one thing you do not do.

That is a morning's work and it will do more than a quarter of additional output. The broader diagnosis, if the problem runs deeper than the writing, is in why your brand looks generic and the power of restraint.
